DELIVERY APPARATUS.

Application filed Gctober 6, 1921. Serial No. 505,734.

To all whom it may concern: I show a loosely swinging door 1.? hinged Be it known that I, (loner G: HiinnoLD, a at 18 and swinging loosely so as to normally citizen of the United States, and a resi hang down, as in Figure 1, when there is dent of Newark, county of Essex, and State no pressure in the receptacle, and which 5 of New Jersey, have invented certain new easily swings shut when pressure is present.

and useful Improvements in Delivery Ap- An air pipe 19 delivers air under presparatus, of which the following is specisure to the receptacle through a suitable air tication. inlet device usually mounted on the top 15,

This invention relates to an apparatus said inlet device including a valve casing 20 J for delivering articles to distant points, and mounted on a nipple 21 and having a valve while its uses may be varied to suit circum 22 therein actuated by a stem 23. T he stem stances, it is particularly devised for use is connected to a lever 2 pivoted at 25 and on steel structural work and in ship buildhaving a handle 26. ing for delivering hot rivets from the forge I also provide a means for controlling the 15 where they are heated to the place where air valve and which means also shuts o'l'i' the they are to be inserted in the structure, so air when the article has been delivered from that they are. delivered quickly and are thus the pine 13. The means comprises a chaindelivered very hot. her or casing 27 which opens into the recephe invention is designed to provide an tacle and is provided with a piston 28 conapparatus of this kind in which, after the nected by a pistonrod 29 with the lever 24-. rivet is delivered to it, a handle is operated The ball 30 forms a convenient and simple which admits air, the air in turn closing the rocking connection between the piston and receptacle in which the rivet was deposited the piston rod. The spring 31 yieldingly and forcing the rivet through to its desholds the piston normally down, and the 5 tination, and when the rivet is delivered spring may be adjusted. and consequently this fact is indicated by reason of the re the opening out the valve may be regulated, ceptacle opening to receive another rivet. as by screw 32 against which the spring The invention is illustrated in the aceomabuts through the medium of the backing panyinr drawing, in which Figure 1 is a side plate 33.

A failure of the door to open shows that there is a stoppage in the pipe and thus prelacin of more than one rivet in .though it is delivered to a point, distant from the forge, and is particularly applicable to large steel structures in building operations and also in ship-yard Work, permitting the installation. of the forge on an upper deck and delivering rivets to various points in the boat, particularly to the work near the keel, where, when forges are in stalled at these low points, the fumes from the forge make it uncomfortable and. sometimes dangerous for the workmen employed there.

It will be. understood that changes can be made in the proportions and arrangement of the parts Without departing from the scope of the invention.

I claim:

1. A delivery apparatus comprising a receptacle having a delivery pipe adapted to receive and transmit a rivet that approximately fits the pipe without the use of a carrier, an air inlet valve, manually operatedmeans for opening the valve, retaining means operable by pressure from within the receptacle for holding the valve open, and a door on the receptacle normally open and arranged to be closed automatically by pressure from within the receptacle.

2. A rivet delivery apparatus comprising a receptacle having a rivet-receiving door normally open, an air" inlet valve normally closed, a delivery pipe adapted to succes sively transmit rivets of a size to substantially fill the pipe, and means for opening the valve, to admit air whereby each rivet is propelled and the door is shut by the pressure of air admitted, the door being arranged to return automatically to its normal open position after each rivet is discharged from the pipe.

3. A delivery apparatus comprising a re ceptacle adapted to receive hot rivets having an inwardly opening door, a manually operable air inlet means adjacent the door,

whereby air is admitted under pressure in' ed to be closed by pressure in the receptacle,

an air inlet means on said receptacle, manually operated means for said inlet means, and air-operated means for holding said in let means open until the rivet leaves the pipe and means for automatically closing said air inlet means after the rivet leaves the pipe.

5. A delivery apparatus comprising a hopper-like receptacle, a delivery pipe on said receptacle, a door in said receptacle and opening inwardly, an air inlet means, a yielding means for normally holding the inlet means shut, and means operable by air under pressure in the receptacle for opening the air inlet means against the force exerted by said yielding means.

(3. A delivery apparatus comprising a hopper-like receptacle, a delivery pipe on said receptacle, a door in said receptacle and opening inwardly, an air inlet means including a manually operable valve, a swing ing handle on the valve, a chamber having an end opening in the receptacle, a piston in said chamber, a spring beyond. the piston, and aconnection from the piston to the handle.

7. A delivery apparatus comprising a hopper-like receptacle, a delivery pipe on said receptacle, a door in said receptacle and,

opening inwardly, an air inlet means including a manually operable valve, a swinging handle on the valve, a chamber having an end opening in the receptacle, a piston in said chamber, a spring beyond the piston, means for adjusting the spring, and a connection from the piston to the handle.

In testimony that I claim the foregoing, I have hereto set my hand, this th day of October, 1921. JOHN G, HARROLD.
